Looks like this one has a good chance of happening given the pattern of press speculation in Italy. They want Tevez AND; A left sided winger/striker would be a good fit for us. That said I think Nasri will be gone if it does happen. Probably about £18m + Tevez (£13m).
It won't effect any deal for Isco - who can play anywhere across the park. And it would give us at least two players who can play anywhere across the park
Navas - right footed.
Milner - right footed.
Iso - Two footed - Stronger right foot.
Silva - Mainly left footed.
El Shaarawy - left footed.
(inverted or normal formation it gives us all options)
It would also indicate that we would have multiple formation options in a game (4-3-3, 4-2-3-1 and 4-1-4-1) - blowing away the problems we encounter in the Prem.
BTW I'm fairly convinced that Milner will eventually play RDM - especially when Barry leaves in 1 or 2 years time.
I also think that we will lose one of the 4 front line striker positions we have had. As there will only be 1 out and out starting striker doing forward.
